Accordingly, the heat-exchanged air may be discharged toward the outlet 22 through the second outlet flow path P22.
- the discharged air has an airflow that rises due to the convection. Accordingly, the upper side of the room is easily heated by the influence of the discharged-warm air, but it is difficult to heat the lower side of the room because the lower side of the room is not affected by the discharged-warm air. In other words, due to the updraft, it may be difficult for the discharged air to reach the floor of the room. Particularly, in the case of a room with a high ceiling, heating efficiency may be very low, and a separate component (e.g., a kit for high-ceiling) may be required to increase heating efficiency.

- the discharged air may be discharged through only the second outlet flow path P22 without passing through the first outlet flow path P21. That is, because the discharged air is discharged through the flow path including a relatively small area, the discharge speed may be increased.
- the air discharged through the outlet 22 may be discharged at a high speed and reach a greater distance. That is, during the heating operation, the discharged air may reach the floor of the room, and thus the entire room may be evenly heated and the heating efficiency may be significantly improved.
- the disclosure is not limited thereto, and the sub-blade 120 may be arranged to block the first outlet flow path P21 for rapid cooling even during a cooling operation.
- the blade unit 100 may rotate within a predetermined angle range to discharge air in various ways.

That is, it is possible to implement a windless airflow. Accordingly, the air conditioner 1 may perform air conditioning while preventing the user from directly facing the wind, thereby improving user satisfaction.
- the blade unit 100 may guide the discharged air to allow cold air to be discharged as horizontally as possible. Cold air goes down due to the convection, and thus the user is directly exposed to the cold air, which may increase the user's discomfort. Accordingly, the blade unit 100 may guide the discharged air to prevent the cold air from directly discharging downward, thereby reducing the user's inconvenience.
- the blade unit 100 may be arranged as illustrated in FIG. 9 .
- the blade unit 100 may guide the discharged air to allow warm air to be discharged downward as much as possible.

- the main-blade 310 may further include a plurality of outlet holes and/or grilles penetrating the main-blade body 311.
- the blade unit 300 may implement a windless airflow by discharging air through the plurality of outlet holes and/or grilles.
- the sub-blade 320 may be provided to adjust the discharge speed of the air discharged through the outlet 22.
- the sub-blade 320 may be provided to block a portion of the outlet flow path P2.
- the sub-blade 320 may be provided to block the first outlet flow path P21.
- the sub-blade 320 may increase the speed of the air discharged through the outlet 22 by reducing the area of the flow path through which the air is discharged. Accordingly, because the air is discharged through the outlet 22 at a high speed, the air may reach a greater distance. Therefore, in the heating operation, the warm air may reach the lower portion of the room, thereby increasing the heating efficiency of the entire room.
- the sub-blade 320 may include a sub-blade body 321 and a connector 322 extending from the sub-blade body 321.
- the connector 322 may include the second gear 325.
- the second gear 325 may be provided to mesh with the first gear 315 of the main-blade 310.
- the second gear 325 may rotate in the second direction R2 by the rotation of the first gear 315 in the first direction R1.
- the blade unit 300 may further include a hinge 350 and a connecting rod 360.
- the hinge 350 and the connecting rod 360 may move in accordance with the rotation of the main-blade 310.
- the hinge 350 and the connecting rod 360 may guide the movement of the sub-blade 320 to allow the sub-blade 320 to rotate in the second direction R2.
- the hinge 350 may be rotatably coupled to the main-blade 310, the sub-blade 320, and the connecting rod 360, respectively.
- the hinge 350 may include a first coupler 351 rotatably coupled to the main-blade 310.
- the first coupler 351 of the hinge 350 may be coupled to a protrusion 3150 protruding from the first gear 315.
- the hinge 350 may include a second coupler 352 rotatably coupled to the sub-blade 320.
- the second coupler 352 of the hinge 350 may be coupled to a protrusion 3250 protruding from the second gear 325.
- the hinge 350 may include a third coupler 353 rotatably coupled to the connecting rod 360.
- the third coupler 353 of the hinge 350 may be coupled to one end 362 of the connecting rod 360.
- a coupler between the hinge 350 and the main-blade 310 may be referred to as a first joint 11
- a coupler between the hinge 350 and the sub-blade 320 may be referred to as a second joint J2
- a coupler between the hinge 350 and the connecting rod 360 may be referred to as a third joint J3.
- the connecting rod 360 may include a connecting rod body 361.
- One end 362 of the connecting rod 360 may be rotatably coupled to the hinge 350.
- the one end 362 may be coupled to the third coupler 353 of the hinge 350.
- the one end 362 may be provided to rotate the hinge 350 according to the rotation of the main-blade 310.
- the other end 363 of the connecting rod 360 may form a second rotation center P.
- the other end 363 of the connecting rod 360 may rotate with respect to the second rotation center P.
- the second rotation center P of the connecting rod 360 is located in front of the first rotation center O of the main-blade 110, that is, the blade unit 300 is a front type, but is not limited thereto.
- the blade unit 300 may be provided as a rear type in which the second rotational center P of the connecting rod 360 is located at the rear of the first rotational center O of the main-blade 110.
- the main-blade 310 may receive the rotational force from the motor 130 to rotate in the first direction R1.
- the second gear 325 of the sub-blade 220 may mesh with the first gear 315 and rotate in the second direction R2.
- the first coupler 351 of the hinge 350 may move forward and upward.
- the connecting rod 360 may rotate with respect to the second rotation center P.
- the third coupler 353 of the hinge 350 may be lifted by the rotation of the connecting rod 360, and the hinge 350 may rotate in a predetermined range in the second direction R2. Accordingly, the sub-blade 320 may move backward. That is, the hinge 350 and the connecting rod 360 may guide the sub-blade 320 to allow the sub-blade 320 to rotate stably in the second direction R2.
- the main-blade 310 may further rotate in the first direction R1, and the sub-blade 320 may further rotate in the second direction R2 in comparison with FIG. 23 . Accordingly, the blade unit 300 may guide the air to be discharged to the further lower side. Further, the sub-blade 320 may block the rear of the outlet flow path P2 while rotating in the second direction R2. That is, by blocking the first outlet flow path P21 of the outlet flow path P2, an area of the flow path, through which air is discharged, may be reduced. The heat-exchanged air may be discharged toward the outlet 22 through the second outlet flow path P22. Accordingly, during the heating operation, warm air may reach a greater distance at a high speed.
- an angle between the main-blade 310 and the sub-blade 320 may be the maximum angle.
- the angle between the main-blade 310 and the sub-blade 320 may be provided in a range of approximately 120° to 180°. However, the disclosure is not limited thereto, and may be provided at about 180° or more.
- the first side 310a of the main-blade 310 and the first side 320a of the sub-blade 320 may be provided to be close to or in contact with each other.
- the second side 320b of the sub-blade 320 may be provided to be close to or in contact with the first guide member 13 of the housing 10.
